Abandoned Coal Mine Investigation

A municipal landfill located in the Valley and Ridge Province encountered an air shaft in a coal bed while constructing part of a landfill cell. Subsequent investigations revealed the opening to an abandoned mine in a draw to the north of the cell. The dip of the strata was toward the cell, raising concerns about potential mined areas beneath the cell. DAA (formerly ATS) was retained to perform geologic mapping and geophysical analysis to determine the extents of the mine beneath the landfill cell.
